Micronaut 4.3.6 breaks custom serializer for bounded generic types

[SpikeBlues]

Expected Behavior

For a bounded generic type (e.g. Point<T extends Serializable>), implementing a custom Serde as depicted in the micronaut-serialization documentation should allow serialization to work properly.
This has been the case with Micronaut version up to 4.3.5.

Actual Behaviour

After upgrading to 4.3.6+, we got following error with the same code base:

io.micronaut.serde.exceptions.SerdeException: No serializable introspection present for type Point.
Consider adding Serdeable. Serializable annotate to type Point. 
Alternatively if you are not in control of the project's source code, you can use @SerdeImport(Point.class) to enable serialization of this type.

However, when the generic type is unbounded (e.g. change to Point<T> instead), the test passes.

It seems the behavior has changed since #742 in terms of matching generic argument types.
